3. Errata and Design Migration Guidelines
The following errata apply to Revision C devices only. See "5. Ordering Guide" on page 25 for more details. No
errata exist for Revision D devices.
3.1. Power Supply Bypass Capacitors (Revision C and Revision D)
When using the ISOpro isolators with power supplies > 4.5 V, sufficient VDD bypass capacitors must be present on
both the VDD1 and VDD2 pins to ensure the VDD rise time is less than 0.5 V/µs (which is > 9 µs for a > 4.5 V
supply). Although rise time is power supply dependent, > 1 µF capacitors are required on both power supply pins
(VDD1, VDD2) of the isolator device.
3.1.1. Resolution
This issue has been corrected with Revision D of the device. Refer to “5. Ordering Guide” for current ordering
information.
3.2. Latch Up Immunity (Revision C Only)
ISOpro latch up immunity generally exceeds ± 200 mA per pin. Exceptions: Certain pins provide < 100 mA of latch-
up immunity. To increase latch-up immunity on these pins, 100  of equivalent resistance must be included in
series with all of the pins listed in Table 13. The 100  equivalent resistance can be comprised of the source
driver's output resistance and a series termination resistor. The Si8410 is not affected by the latch up immunity
issue described above.
3.2.1. Resolution
This issue has been corrected with Revision D of the device. Refer to “5. Ordering Guide” for current ordering
information.
